3 shot course: Safe to take, even if not needed the second time around. May be given the rx if 1st course didn't work, or was interrupted.

Yes: Small percentage of people do not develop adequate response to the hepatitis b vaccine, even after three doses. They can get another series of vaccination especially if affected individuals are at high risk to get infected with hepatitis b.
